(b) Туре I еrror. 2. In a manufacturing plant, plastic sheathing is specified to be at least two mils thick by one of the many quality measures. Set up the null and alternative hypothesis for a quality monitoring system that ensures the desired level of quality. 3. Determine whether following statements are type I or type II error.
